Abstract:
Design of buildings to withstand wind loads necessitates meeting criteria for two limit states: serviceability under frequent loads and strength under extreme loads. Performance-based wind design (PBWD) represents the state-of-the-art approach to wind design that provides a comprehensive framework for estimating wind load, assessing structural dynamic response, and achieving safe and cost-effective design solutions. This paper presents an overview of the current design methodology and the associated challenges in addressing serviceability wind design concerns, particularly for tall buildings with reinforced concrete structural systems. Firstly, the wind actions on buildings are briefly outlined in this paper, and the limit states and criteria governing the serviceability wind design, including comfort, deformation, and strength considerations, are discussed. Additionally, the inherent connections between serviceability wind design and seismic design for tall buildings are elaborated. Subsequently, the requirements for wind hazards, structural modeling, analysis technique, damping, and stiffness modification factors are explained. Finally, a detailed examination of serviceability wind design is provided through a case study involving a reinforced concrete tall building for further insight and discussion.
